mrkinnies, I've been traveling for several days, finally had a chance to sit down an check your responses to my last post as well as those of others.
You attempted to dodge most of my post in reference to the complete absence of peer-reviewed engineering papers addressing the theories you propose. This absence still remains unexplained and unaddressed by you.
I will take your inability to respond directly as an admission that there is NOT A shred of professional, peer-reviewed science to back up your claims. Else you would have provided it quickly, I suspect.
This is very damaging to your credibility, because it seems all you bring to the table are the same tired truther arguments from incredulity, bare assertions and various logical fallacies.
Leaving that failure, I'll just comment on your rather desperate reliance on the concept of 'symmetry' in the WTC 7 collapse as some kind of pseudo-engineering proof of CD.
Firstly, you have not established, with any reference to controlled demolition literature, professional testimony or otherwise, that 'symmetry' is actually any kind of metric that can be usefully applied to a building collapse in aid of determining whether a controlled demolition occurred or not.
It appears that the word 'symmetry' is being wielded as a term of obfuscation, or as a 'magic' property to trump any other discussion or evidence available.
The main confidence that competent observers would have that your use of this word is meaningless lies in the fact that many real controlled demolitions are not symmetrical at all. Depending on the structure, demolition engineers will deliberately cause sections to fail first, walls to implode in certain directions etc... but clearly
symmetry is not a necessary component of this.
Further, your attempt to use a tiny portion of the 2008 NIST report on WTC 7 in support of your argument is ludicrous, in light of what the report actually says about the failures, and that it specifically posits a progressive,
highly asymmetrical internal collapse leading to the final global collapse.
I believe you've even referred glibly to the collapse of the E Penthouse as if there were no significance to the overall collapse. Now that's just bizarre, since you claim to have read the report.
In essence, you quotemine the report to the point where its observations are contradicted and distorted. One thing that an honest reader of the report will surely see; that certain aspects of the collapse were highly asymmetrical, and others were almost symmetrical.
Again, while interesting, it tells you absolutely nothing about the relevance of high explosives to this collapse, and you, as the arguer of CD theory in WTC 7's collapse, have offered nothing further.
Apparently you need to be reminded AGAIN that you are proposing some kind of never-before-seen technique whereby
explosives are used throughout the course of several hours, whilst random fires are raging on various floors, to 'weaken' key structure in preparation for a final command to bring the building down at about 5:20pm!!!
Nevermind you haven't got a technical leg to stand on regarding the first part, having been unable to cite ANY professional CD engineer who has published a thorough, documented paper in support (and thus relying only on your unqualified judgement), but with regard to the proposed 'final command' required by your theory,
YOU CANNOT PROVIDE A SHRED OF EVIDENCE THAT THIS IN FACT HAPPENED!!!!!
You lack:
1) Explosive sounds at the time you require the supports at 'all four corners' of the building to be destroyed
2) Any visual evidence of such required explosions or 'squibs' at the necessary floors (which of course you haven't even discussed intelligently)
3) Any technical backing that this would even be possible
To me, as a skeptic, your 'symmetry' argument is a giant red herring, just as 'freefall = CD' is. Neither concept has any actual technical backing from the engineering and controlled demolition literature or professional journals. These terms are no more than catchy, sciencey-sounding labels which perhaps can persuade the uneducated or casual observer.
But you'll have to do much, much better than this to persuade those will real expertise and interest in the subject. I predict you haven't got even a sliver of hope in doing this, and as such your opinions will remain confined to obscure internet forums.
Best of luck though - I grant you that 'even a stopped clock is right twice a day', so who knows? You may actually be correct once in a while.
